Unbeknownst to Chinnarasu, his late mother had bequeathed her wealth to him through a deed, stipulating that he could only sell these assets after his marriage.

At present, Chinnarasu matures into a principled young man, albeit an illiterate one, who implicitly obeys Nagamani's instructions.

As night falls, Chinnarasu and his companion, Mannangatti, are allowed by Rukmini to stay there overnight when she learns that they are from the village where she is soon to be married.

The next morning, Sathyagounder returns home and Chinnarasu is shocked to discover that the actual groom is not him, but his stepbrother, Gnanasekar.

At the marriage hall, Gnanasekar unexpectedly flees, forcing Sathyagounder to request Chinnarasu to marry Rukmini to which he reluctantly agrees.

Nagamani devises another plan with her son, Gnanasekar, to swindle Chinnarasu's wealth under the guise of building a hospital.

During the hospital's inauguration ceremony, a shocking revelation emerges: Gnanasekar had abandoned his degree and is ineligible to practice medicine, having pretended to be a doctor all along.

Chinnarasu intervenes beating Nattarayan and making him marry Mannangatti's sister whom he had previously deceived.

Nagamani's accomplices lock Chinnarasu in a room and threaten Rukmini demanding her to sign over the family's assets.

However, Nagamani transforms, ordering her accomplices to release Chinnarasu and acknowledging her mistakes due to her obsession with wealth.

[6] The film became a major breakthrough for Saraswathi, so much that the general public began referring to her as "Aatha" (stepmother) the way the character is addressed onscreen.
